Use of the special case "when is [blah] on call" does not return correct results

[cboscolo]

We have only one PagerDuty schedule defined called "Normal"

Resulting in:
cboscolo [9:38 AM] pagerbot when is cboscolo on call
pagerbotBOT [9:38 AM] CBoscolo is not scheduled to go on any schedule

But if I reference our schedule by name it works.
cboscolo [9:39 AM] pagerbot when is cboscolo on Normal
pagerbotBOT [9:39 AM] CBoscolo goes on call at 5:00 PM Feb 10 (-0800) for schedule Normal

This was tested after updating to: 736a89c

Does your schedule belong to an escalation policy?

[cboscolo]

Yes, two escalation policies use this schedule.
